7050 aluminum plate is a high-strength heat-treatable alloy with extremely high strength and resistance to peeling corrosion and stress corrosion fracture. Commonly used in aircraft structural components for medium and thick plate extrusion parts, free forging parts, and die forgings. The alloy requirements for manufacturing such parts are: strong resistance to peeling corrosion, stress corrosion cracking, fracture toughness, and fatigue resistance
